Useful Management Information

The FeNO test can detect eosinophilic airway inflammation, determine the likelihood of corticosteroid responsiveness, monitor airway inflammation to determine the need for corticosteroids and identify non-adherence to corticosteroid therapy.

Indications:

Assess the etiology of respiratory symptoms.
Help identify the eosinophilic asthma phenotype.
Assess the potential response or failure-to-respond to anti-inflammatory agents, notably inhaled corticosteroids.
Establish a baseline FeNO during clinical stability for subsequent monitoring of chronic persistent asthma.
Guide changes in doses of anti-inflammatory medications step-down dosing, step-up dosing or discontinuation of anti-inflammatory medications.
Evaluate adherence to anti-inflammatory medications.
Assess whether airway inflammation is contributing to poor asthma control, particularly in the presence of other contributors (e.g. rhinosinusitis, anxiety, gastro-esophageal reflux, obesity and continued allergen exposure).

Clinical advice:

Cigarette smoking suppresses FeNO which limits its use in smokers.
